Insight into the Mechanistic Basis of the Hysteretic-Like Kinetic Behavior of Thioredoxin-Glutathione Reductase (TGR)

Figure 6

Dependence of the apparent lag time on the concentration of both NADPH and GSSG. The magnitude of the relaxation time was estimated as described under Materials and Methods from full time courses performed at 25°C and pH 7.8 at the following NADPH concentrations: (Δ) 5.5 μM; (▲) 9 μM; (○) 15.5 μM; (●) 50 μM. Each point represents mean ± standard deviation (n=6).
